Also, you can calculate the water flow rate in liters per minute as follows: For example, if your water flow sensor generates 450 pulses for one liter of water flowing through it and you get 10 pulses for the first second, then the elapsed water flow rate is 10/450 = 0.022 liters per second or 0.022 * 1000 = 22 milliliters per second. If a water flow meter is not installed correctly, it wont work properly, so if you have any questions relating to installation, please dont hesitate to contact us. endstream

Connect the threaded side of the PVC connectors to both ends of the water flow meter. Arduino can read digital pulses by generating the water flow meter through the DATA line. *, This form collects your name, telephone number and email address so that we can communicate with you and provide any assistance required. Use jumper wires with male and female headers as follows: You can directly power the water flow sensor using Arduino since most of the residential type water flow sensors operate under 5V and consume a very low amount of current. With hundreds of different water flow meters to choose from, once youve decided which one to purchase the next question is: how do you install a water flow meter?
